Mercury is one of the most toxic heavy metals in the environment. It is therefore important to routinely monitor the Hg level in many types of samples. The US EPA approved methodology for the determination of Hg uses the cold vapor technique with stannous chloride as the reducing agent1. This methodology is applicable to Hg determinations in a range of waters (drinking, ground, surface, sea and ...

Increasingly stringent NOx regulations have required plant operators to modify traditional combustion processes. SOx regulations and deregulation have forced plant operators to diversify their coal sources. And new mercury control requirements have been instituted by the U.S. Environmental Protection Agency. These changes challenge plant operators who are trying to achieve the low carbon levels ...

Next week the U.S. Environmental Protection Agency is expected to finalize new rules to reduce mercury and other toxic air emissions that will affect dozens of antiquated power plants currently operating without pollution controls. These rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will new EPA ...

Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process.

However, they’re in the electronics we use every ...

ABSTRACT Prior to constructing a new FOTW, Fort Knox had a history of exceeding KPDES effluent limitations for ammonia and BOD. The new 6 MGD FOTW solved the problem, but metals exceedances became an issue. The exceedances could be linked to several factors: low water-quality based effluent limitations (WQBELs) on the new KPDES permit, high background concentrations of some metals, and high ...

Jersey Island, British Isles, is a popular tourist destination for Europeans. It’s the largest of a series of small, independent islands in the English Channel near the coast of Normandy.

Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

Despite considerable improvements in the past decades, Europe is still far from achieving levels of air quality that do not pose unacceptable risks to humans and the environment. Air pollution is the top environmental risk factor of premature death in Europe; it increases the incidence of a wide range of diseases and has several environmental impacts, damaging vegetation and ecosystems. This ...
